But that characterization of
seawater
desalination as being a nonstarter is hopelessly out of date.
We've made tremendous progress in
seawater
desalination in the past two decades.
This picture shows you the largest
seawater
desalination plant in the Western hemisphere that's currently being built north of San Diego.
Compared to the
seawater
desalination plant that was built in Santa Barbara 25 years ago, this treatment plant will use about half the energy to produce a gallon of water.
But just because
seawater
desalination has become less energy-intensive, doesn't mean we should start building desalination plants everywhere.
And we can make up the difference through a combination of stormwater harvesting and
seawater
desalination.
When carbon dioxide dissolves in seawater, it undergoes a number of chemical reactions.
But I'll tell you as more carbon dioxide enters the ocean, the
seawater
pH goes down.
As more carbon dioxide has entered the ocean, the
seawater
pH has gone down, which basically means there has been an increase in ocean acidity.
And then we can collect our
seawater
samples in these large bottles.
We take the
seawater
back on the deck, and then we can either analyze them on the ship or back in the laboratory for the different chemicals parameters.
One of the big concerns is as ocean acidity increases, the concentration of carbonate ions in
seawater
decrease.
They also need these carbonate ions in
seawater
to make their coral structure in order to build coral reefs.

seawater
as when you use it industrially.
In fact, they naturally improve water quality, filtering it as they feed off of sunlight and nutrients in the
seawater.
One setting offers protection from this radiation and an alternative energy source: the hydrothermal vents that wind across the ocean floor, covered by kilometers of
seawater
and bathed in complete darkness.
A hydrothermal vent is a fissure in the Earth’s crust where
seawater
seeps into magma chambers and is ejected back out at high temperatures, along with a rich slurry of minerals and simple chemical compounds.
The
seawater
expelled here is highly alkaline and lacks carbon dioxide, but is rich in methane and offers more hospitable temperatures.
Bottles made of polyethylene terephthalate, PET, will sink in
seawater
and not make it this far from civilization.
They will float in seawater, but unfortunately do not get recycled under the bottle bills.
Small bits of plastic concentrate persistent organic pollutants up to a million times their levels in the surrounding
seawater.
This nearby city of Balikpapan has a big problem with water; it's 80 percent surrounded by seawater, and we have now a lot of intrusion there.
And the reason it works so well is that the seaweed makes the
seawater
less acid.
